Normally, if your windows drivers are correctly installed/reinstalled and you power off and then connect the phone to the computer, SF Flashtool should be able to flash the ROM again. If this does not work (and you have reinstalled all windows drivers, just as a precaution), I am not sure what to do.
I used SF Flash version 1604 on my windows 10 x64 because newer version of the tool crashed too frequently.
